Patented Mar. 17, 1931 PATENT OFFICE RAYMOND GEOFFROY, OF ARCTIC, RHODE ISLAND WRENCH Application filed June 23,

This invention relates to wrenches and more particularly of the Stillson type, and the primary object thereof is to provide a wrench which is effective in gripping the work regardless of whether the latter be located centrally of the gripping jaws or adjacent the ends thereof, thereby to facilitate operation of the wrench.

A further object of the invention is to provide a wrench which is devoid of springs or the like and wherein the jaws have an increased gripping action on the work thereby to eliminate slippage.

The invention further aims to simplify and improve a wrench of this type and to also provide a construction in which a minimum of parts are employed that are compactly assembled and which are not subject to derangement in use.

In the drawings Figure 1 is a side elevation of the invention partly broken away and in section; and

Figure 2 is a front side edge elevation.

In proceeding in accordance with the present invention a handle 1 is employed which at its upper end is provided with a short extension 2 located at the rear of the handle, while the front of the handle is formed with a socketed portion 3 the latter located at the short base of the extension 2 and at the front of the handle and having a closed bottom. The inner jaw 4: has a short tail 5 depending therefrom which latter at its free end is conformably engaged in the socketed portion 3. The outer jaw 6 has a shank 7 threaded as is customary at 8 and receives thereover the usual nut 9. A yoke 10 is apertured to receive the shank 8 of the jaw 6 and also the nut 9 and to its lower portion is pivoted at 11 to the extension 2 of the handle 1 while its upper portion is pivoted at 12 to the jaw 4 intermediate the ends of the latter. It will thus be noted that the parts are compactly assembled and the wrench generally follows the usual customary appearance of one of this type, the jaw 4.- being located within the confines of the handle 1 as clearly shown in Figure 1.

In operation, upon downward movement of the handle 1 in work gripping position of 1930. Serial No. 463,265.

the wrench the latter through the socket 3 will impart an endwise thrust to and thereby rock the jaw 4; toward and against the work and at the same time the handle due to the pivotal connections of the adjustable or outer jaw thereto and to the inner jaw 4 will cause the jaw 6 to be rocked toward the work, thereby causing both jaws to effectively" grip the work.

It will further be observed that there are no springs or other equivalent parts employed and that positive and certain parts of the action results upon downward manipulation of handle 1, so that it is not necessary that the jaws be accurately centered with respect to the work.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is In a wrench, a handle having an integral lateral shelf-like projection closely adjacent its upper end, the upper side of said projection being formed with a socket having a bottom wall, an inner aw having a depending tail with its lower end engaged within the socket, said socket being of such depth as to receive the depending tail and to hold the latter from movement out of the socket in any and all positions of the parts, a yoke pivoted at its lower end to the handle above the projection closely adjacent thereto and at its upper end to the inner jaw and an adjustable jaw carried by the yoke, said lower end of the depending tail being engaged with the bottom wall of the socket so that upon the working stroke of the handle the tail will have an endwise thrust imparted thereto.

In testimony whereof I have signed my name to this specification.

RAYMOND GEOFFROY.
